Is your original balance the one on the bottom of this picture? If so, the 39-187 was the proper match. I do not see a prior correspondence associated with your email, so I'm not sure why we would recommend the 39-089. I apologize for that confusion.

I'm afraid we do not have a version of these operators with a smaller link arm. We have tried searching in the past but had no luck. You have two options available: the first is adjusting the bracket that the link arm attaches to so that it better accommodates the new operator. The second is to put the old link arm on the new operator. To do this, you would need to drill out both arms, then attach the old arm on the new operator with our 62-014.
